Resultant force and Newton's first law
Resultant force and Newton's first law
A free-body diagram shows the forces acting on one object using arrows. The resultant force is the single overall force after all the forces are combined.
Step-by-step lessons on Edexcel GCSE Physics 2.3 Forces and Newton's laws, covering 2.3.1 Newton's first law, 2.3.2 Newton's second law, and 2.3.3 Weight and gravitational field strength. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
